Stabilized convex symplectic manifolds are Weinstein
Yakov Eliashberg, Noboru Ogawa, Toru Yoshiyasu
We show that a stabilized convex symplectic (also called Liouville) manifold with the homotopy type of a half dimensional CW-complex is symplectomorphic to a flexible Weinstein man…
On the neighborhood of a torus leaf and dynamics of holomorphic foliations
Takayuki Koike, Noboru Ogawa
Let be a complex surface and be an elliptic curve embedded in . Assume that there exists a non-singular holomorphic foliation with as a compact leaf, d…
The totally nonnegative part of the finite Toda lattice via a reducible rational curve
Shinsuke Iwao, Kyo Nishiyama, Noboru Ogawa
A totally nonnegative matrix is a real-valued matrix whose minors are all nonnegative. In this paper, we concern with the totally nonnegative structure of the finite Toda lattice,…
Local criteria for non embeddability of Levi-flat manifolds
Takayuki Koike, Noboru Ogawa
We give local criteria for smooth non-embeddablity of Levi-flat manifolds. For this purpose, we pose an analogue of Ueda theory on the neighborhood structure of hypersurfaces in co…
